A hyperparasitoid chalcidoid wasp on the cocoons of its host, a braconid wasp, itself a koinobiont parasitoid of Lepidoptera. Parasitoids can be classified as either endo- or ectoparasitoids with idiobiont or koinobiont developmental strategies. Endoparasitoids live within their host's body, while ectoparasitoids feed on the host from outside.
Hosts may use behavioral evasion when they encounter an egg laying female parasitoid, like dropping off the plant they are on, twisting and thrashing so as to dislodge or kill the female and even regurgitating onto the wasp to entangle it. The wriggling can sometimes help by causing the wasp to "miss" laying the egg on the host and instead ...

They build nests and live in colonies ranging in size from 1 to 18 members. [2] Microstigmus is widely considered to be the only true eusocial species of apoid wasp. [3]

[25] [28] A study in 2020 found that the frequency and duration of tonic immobility was affected by the sex of the wasp and the temperature of the environment, but not the color of the background the wasp ...
A tarantula hawk is a spider wasp (Pompilidae) that preys on tarantulas.Tarantula hawks belong to any of the many species in the genera Pepsis and Hemipepsis. They are one of the largest parasitoid wasps, using their sting to paralyze their prey before dragging it into a brood nest as living food; a single egg is laid on the prey, hatching to a larva which eats the still-living host.
